Unique reclosable flexible-film thermoform for sliced meats

Norwegian food company Orkla addresses food waste with a new flexible-film thermoform for its sliced, cured meats that incorporates a reclosable label on the top web.

One of many recognized causes of consumer food waste is improper storage of products—in particular, refrigerated foods. With the new packaging for its Vossafär sliced, cured meat, Norway’s Orkla Group invested two years in developing a structure that would alleviate this problem. Orkla’s existing packaging was a flexible-film thermoform. While the pack did have an easy-peel opening, it was not resealable.

Orkla’s partner in the project was Mondi. It was charged with creating a reclosable structure that could run on Orkla’s existing thermoforming line with a minimum of modifications. At the outset, Orkla ruled out using a standard reclosable film on the top of the package, as it would be difficult for consumers to line up the top web with the bottom flexible-film web.

Mondi’s challenge, therefore, was to develop a custom, resealable, multilayer barrier film for the top web that would resist curling at the temperatures used in Orkla’s thermoforming line. Its solution was a structure very similar to Orkla’s existing package, but with a resealable label incorporated into the top film web. Users peel back the label, take the portion they want, and then reseal the pack by pressing down on the label.
